Sharon, 85, has been in a coma since 2006 when a stroke incapacitated him at the height of his political power. Amir Marom, a spokesman for Tel Hashomer hospital, where Sharon has been treated for most of the past eight years, said Wednesday that Sharon's medical condition has "deteriorated in the past few days." He refused to elaborate.

Israeli media reported that Sharon was suffering from kidney problems and that his family was at the hospital. In September, Sharon underwent surgery to insert a new feeding tube.

Sharon was one of Israel's most iconic and controversial figures. As one of Israel's most famous generals, Sharon was known for bold tactics and an occasional refusal to obey orders.
